Detect if the Platform SDK is missing when building with Visual C++ Express Edition

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Daniel Bates]

As mentioned on the Improving Life on Windows wiki page <http://trac.webkit.org/wiki/ImprovingLifeOnWindows>, we should detect when the Windows Platform SDK is missing and inform the user. This will also fix the first error listed in <http://trac.webkit.org/wiki/BuildingOnWindows#VisualCExpressEdition>.

Patch

Moved check for Platform SDK into subroutine buildVisualStudioProject from subroutine setupCygwinEnv so that we only check for its existence when we are are going to build. This resolves the issue observed on the Windows Debug (Test) bot where run-webkit-tests is passed the --root argument and thus does not build DRT (hence, there is no need to check for the Platform SDK).

Also, updated the criterion for determining whether the Platform SDK is installed by checking for the existence of its registry entry instead of a fixed install location.

The name of this variable makes it sound like it will only be set to 1 when a build is actually in progress. Maybe $willUseVCExpressWhenBuilding or something like that would be better?

This can be written as:

return if -e $windowsPlatformSDKRegistryEntry;

Will change before I land.
